Description
As a certified reference material (CRM), Thulium2,4-pentanedionate trihydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Thulium2,4-pentanedionate trihydrate (CAS 21826-63-1), molecular formula C15H21O6TmH2O and molecular weight 484.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Thulium2,4-pentanedionate trihydrate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 484.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
